I bet they love those pictures. The kids see the magic that has carried those dancers through all the difficult days.
And about exhausted... Kids do not understand the “tucker out” factor for adults. An exertion like that would be like their recess time to the kids. What, miss ballerina? You’re pooped ALREADY? You look like you were just beginning to have fun!
Maybe they could possibly have their understudies do the photo work?
Oh, the kids do! What’s fascinating is that when you’re close to the dancers, you see how strong and muscled they are - on stage they look like sylphs. And also how completely exhausted. I love ballet.
